TANDBERG TCD 310 Service Manual

3.4 CASSETTE ARM
The cassette arm can be adjusted by bending the
end which normally rests against the cassette
(see figure).
Insert a cassette, close the cassette compartment
and check the following:
— The cassette should rest against the cassette
guides.
— Microswitch MS 4 should be closed. (If neces-
sary, MS 4 can be adjusted by bending the
support bracket for the microswitch).
— The locking lever extending from the cassette
compartment and down through a slot in the
motor support plate should be about 2 mm from
the right end of this slot (see figure).
NOTE! If the cassette arm is bent too much to
the right, the locking lever will be moved so far
to the left that it will not lock the cassette
compartment in the lower position.
— When the cassette compartment is released, the
cassette arm should push the cassette half-way
out of the compartment.
